The 40th anniversary of the last moon landing just after midnight, Dec. 7, 1972 will be celebrated Saturday, Dec. 8 from 12:30 to 3:30 p.m. at the Museum of Natural History and Planetarium at Roger Williams Park. The event features a full dome “Astronaut” planetarium show at 1 and 2 p.m., moon rocks, family activities, and more. Admission to the Museum is free and discounted planetarium admission is $2 for visitors bringing a canned good or gently used book to donate.

The exploration of space is the greatest endeavor that humankind has ever undertaken. What does it take to be part of this incredible journey? What does it take to become an astronaut? This planetarium show takes the viewer from Earth into space ... and beyond! Presented in high-definition full dome digital video with surround sound, "Astronaut" is an adventure. "Astronaut" is narrated by Ewan McGregor and produced by the National Space Center.

The rocks and soil returned by the Apollo astronauts from the Moon contain crucial clues to how the Earth and the Moon formed, the intensity of meteorite impacts, and even the history of the Solar System. Visitors can hold and examine a disk of these scientific treasures under the microscope and learn what processes them. Meteorites and tektites from around the world will be on display.
